3 weeks PO - The incision on top of my butt crack leaks a mucus like fluid

I had a body left/liposuction incl. butt left and injected the fat into it. The cut go around my body and meets on top of my butt crack. the wound healed but the meeting point isn't as good as the others because it's more "humid" there lol When I put a tissue to check that area, i get a mucus like fluid on the tissue "very small amounts".. I am not sure if it's an infection or hygiene, I take a shower every day and clean/sanitize it but it stings a bit which means it's not fully healed inside
